What is the cuticle overlapping the lunula at the base of the nail referred to as?

The term for the cuticle that overlaps the lunula at the base of the nail is referred to as the eponychium. The eponychium is a layer of tissue that serves an important protective function for the nail matrix and the area where the nail grows. It helps prevent bacteria, fungi, and other pathogens from entering the nail bed, thus protecting the health of the nail itself.

In contrast, the hyponychium refers to the skin located beneath the free edge of the nail, while the cuticle often refers generally to any dead skin at the base of the nail. The nail fold encompasses the skin that surrounds the nail on the sides. Understanding these terms and their specific functions is essential for maintaining nail health and providing appropriate care in a nail service context.
